Question:

Consider the MOSFET current-source circuit in Figure P10.44 with $V^{+}=$ $+2.5 \mathrm{~V}$ and $R=15 \mathrm{k} \Omega$. The transistor parameters are $V_{T N}=0.5 \mathrm{~V}, k_{n}^{\prime}=$ $80 \mu \mathrm{A} / \mathrm{V}^{2}, W / L=6$, and $\lambda=0$. Determine $I_{\mathrm{REF}}, I_{O}$, and $V_{D S 2}(\mathrm{sat})$.
